How many moles of N2 are in a flask with a volume of 250ml at a pressure of 300.0 kPa and a temperature of 300.0 K?
To find the number of moles of N2 in the flask, we can first calculate the number of molecules using the ideal gas law equation PV = nRT. Then, convert the number of molecules to moles by dividing by Avogadro's number, which is 6.022 x 10^23 mol^-1. Calculate the number of moles using: n = PV / RT. Given P= 300.0 kPa, V= 0.25 L, T= 300.0 K, R= 8.31 LkPa/(Kmol), the number of moles of N2 can be calculated.
How many moles in a gallon of hydrogen?
210.3 moles of H2 are contained in one gallon of H2O
How many moles are contained in 8.08 L of O2 at standard temperature and pressure?
1 mole of any gas occupies 22.4 L at standard temperature and pressure (STP). Therefore, 8.08 L of O2 at STP would contain 8.08/22.4 = 0.36 moles of O2.
How many moles of NaOH are required to fill a flask with a volume of 27 liters and a temp of 24 degrees celsius and a pressure of 50 kPa?
I'm pretty sure NaOH is a solid under those conditions! You just need to know the density of NaOH. The temperature and pressure are irrelevant if it was a gas, you could use the Ideal Gas Law. See the Related Questions link to the left of this answer about that.
How many moles of chloroform CHCl3 are required to fill a 253-mL flask at 100.0 degrees C and 940 torr?
To find the number of moles of chloroform, you first need to calculate the volume of chloroform at the given conditions using the ideal gas law. Once you have the volume, you can then use the formula n = PV/RT, where P is the pressure, V is the volume, R is the gas constant, and T is the temperature in Kelvin, to find the number of moles.
